Shepherd of Hermas, a 2nd-century Christian writing that is one of the works representing the Apostolic Fathers, Greek Christian writers of the late 1st and early 2nd centuries. The author, Hermas, is known only through the autobiographical details given in the Shepherd. A Christian slave who was given his freedom, he became a wealthy merchant, lost his property, and did penance for past sins. He stated that he was a contemporary of Clement of Rome (possibly Pope Clement I; d. c. 95). However, the Muratorian Canon, the oldest (c. 180) extant list of New Testament writings, asserts that he was a brother of Pope Pius I (d. 155), and internal evidence in the Shepherd seems to support the later date.
The Shepherd records five visions experienced by Hermas, and it is named for the angel of repentance who appeared in the fifth vision dressed as a shepherd. In addition, the work contains 12 mandates (moral commandments) and 10 similitudes (parables). The basic theme is that post-baptismal sin can be forgiven at least once and that a day of repentance is coming, after which sins cannot be forgiven. Concerned with morals rather than theology, the work is a valuable indication of a type of Jewish Christianity—still adhering to the Mosaic Law—evident in Rome during the 2nd century.
It was regarded as scripture by Irenaeus, Clement of Alexandria, Origen, and Tertullian; but the Muratorian Canon denied that it was inspired, and St. Jerome stated that it was known very little in the Western Church. Much more popular in the Eastern Church, the work is contained in the 4th-century Codex Sinaiticus of the Greek Bible. Manuscripts in Greek, Latin, and Ethiopic and fragments in Coptic and Persian exist.
